Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724208, here are decompositions:

  • 47 + 8724161 = 8724208
  • 107 + 8724101 = 8724208
  • 137 + 8724071 = 8724208
  • 257 + 8723951 = 8724208
  • 401 + 8723807 = 8724208
  • 419 + 8723789 = 8724208
  • 569 + 8723639 = 8724208
  • 599 + 8723609 = 8724208

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,724,208 and was likely granted around 2014.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 8724208 first appears in π at position 884,239 of the decimal expansion (the 884,239ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
